Remote User Interface Adaptation for Multimedia Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in dynamically adapting user interfaces (UIs) to various multimedia devices' environments and characteristics, leading to inefficiencies in UI transmission and reception, particularly in remote control scenarios.
Innovation Solution
A method and apparatus that determine the representation level of a UI requested by a client, assess its availability, and generate or provide a UI tailored to the client's environments and characteristics, using a UI server and client communication system supporting Remote User Interface (RUI), employing MPEG standards for encoding and decoding UI data.

Engineering Contradiction Analysis
1Adaptability or versatility
If a UI server provides a control UI to a UI client in a conventional remote control system, then the UI transmission can be performed, but the UI cannot be dynamically adapted to various multimedia devices' environments and characteristics
Solution Approach 1:
The system dynamically adapts UI representation levels based on client device characteristics and environmental factors. The UI server determines appropriate representation levels (e.g., full UI, simplified UI, icon-only UI) based on real-time assessment of client capabilities, network conditions, and device types, allowing the UI to transform from static to adaptive state.
Solution Approach 2:
The patent changes the representation level parameter of the UI based on client device characteristics. By adjusting parameters such as UI detail level, information density, and interaction complexity, the system optimizes UI transmission for different devices without requiring complete UI redesigns.
2Productivity
If the UI server transmits detailed UI information to all clients, then complete control functionality is provided, but transmission efficiency decreases and network bandwidth is wasted
Solution Approach 1:
The system extracts and transmits only the essential UI elements required for each client device based on its capabilities. Instead of transmitting complete UI packages to all clients, the server identifies and sends only the necessary representation level (e.g., transmitting icon representations to simple devices while providing full UI to capable devices).
Solution Approach 2:
The patent applies partial action by transmitting UI information at appropriate representation levels rather than always providing complete UI details. This ensures that each client receives sufficient information for its specific needs without overwhelming it with unnecessary data.
3Ease of operation
If the UI is customized for each client device, then user satisfaction improves, but the complexity of UI generation and management increases
Solution Approach 1:
The patent implements a universal UI framework that can serve multiple client types through a single system architecture. The UI server maintains a standardized set of UI templates and representation levels that can be adapted to various device types (TVs, set-top boxes, mobile devices, tablets), eliminating the need for separate UI development for each device category.
Solution Approach 2:
The system performs preliminary classification of client devices and pre-determines appropriate UI representation levels before actual UI transmission. By assessing client characteristics in advance and selecting appropriate representation levels beforehand, the system reduces real-time processing complexity while maintaining customization benefits.

AI summary
A method and apparatus for transmitting a User Interface (UI) to a client in a communication system supporting a Remote User Interface (RUI), in which a representation level of a UI requested by the client is determined, whether the representation level is available in a service provided to the client is determined, and a UI having an available representation level is provided to the client, according to the determination results.
